GTX 980 DisplayPorts?

theoreticalninja · January 30, 2017

I just recently purchased a Asus Strix GTX 980 off of Craigslist for $240. Everything works just fine except I cannot get the DisplayPorts to recognize any of my displays. I am using 3, Vantec DisplayPort 1.2 to 4K HDMI 2.0 Active Adapters that I purchased on Amazon since none of my monitors have DisplayPort. I also have some passive Cable Matters adapters that I tried which also do not work. Does anyone have any suggestions about what I should do? I have a 4, 1080p monitor setup and I am only able to use 2 of them.

I've been in contact with the seller and he had the same issue with the card. The only way he was able to get it to work was to use this adapter:

I've tried all three DisplayPorts and none of them will recognize the monitors through an adapter. It would seem weird for all three to be broken.

The DVI and HDMI ports work just fine however.

The card has an onboard HDMI output also, try connecting the monitor straight and then check if the monitor works. Might be the adapters are not working. You plugged in the USB dongle also?

Yes. Both the DVI and HDMI ports work just fine. ...(I updated the original post to have a link to the card in question)... I am not having any issues with those. The seller also stated that the display ports worked with his 4k monitor since the monitor had DisplayPort inputs. I have tried all of the adapters that I own. 3 of the Vantec adapters linked above (I doubt all 3 would be faulty), 2 different Cable Matters (have been verified to work with the GTX 660 that my 980 is replacing), as well as a DisplayPort to DVI adapter. None of the adapters require external power. The Vantec active adapter states that it is self powered and does not need any external power source.
